An accurate method is proposed for evaluating the index dispersion and field distribution within a Ti: LiNbO3 slab waveguide. The derivation is based on analytical solutions of the wave equation. The propagation characteristics are obtained using Fuchs' theorem which allows the solution of the boundary-value problem, with the desired degree of accuracy, for any analytically expressed refractive-index profile, even in the cut-off regions. Only a few minutes of computer time are required to draw the dispersion curves and field distribution using a VAX system.
